Description

A kind of disinfection sterilizing type medical supersonic couplant and preparation method thereof
Technical field
The present invention relates to the preparation of couplant between medical treatment instrument probe and the human body skin, be specifically related to a kind of disinfection sterilizing type medical supersonic couplant and preparation method thereof.
Background technology
The function of traditional medical ultrasonic coupling agent is the coupling of strengthening between ultrasonic probe and the human body skin, and isolated ultrasonic probe and be examined air between the skin of position makes the sound wave conduction not be subjected to air influence and decays, to reach good detection effect.CN1087016A disclosed " preparation method of medical ultrasonic coupling agent " be get earlier 5 the gram CPB-1 be that acrylate copolymer (being carbomer-1 type material) was put into water 5~6 hours, after it is expanded, adding 20% sodium hydroxide solution makes its pH value between 6.8~7.2, then, add sodium benzoate and glycerol, stirring adds water to 1000ml.Medical ultrasonic coupling agent with this method preparation is the same with traditional medical ultrasonic coupling agent, does not have the function of sterilization.The sterilization of ultrasonic probe is to perplex a great problem that medical supersonic detects always, and main cause has three:
(1) no suitable compound, the particularity of ultrasonic probe material, the disinfectant that has determined at present great majority on the market that these plastics and rubber are had corrosivity and a swellability can not be used for the sterilization of ultrasonic probe;
(2) no suitable medium, the particularity of structure of ultrasonic makes it can not use the most frequently used infusion method to carry out disinfection, to the requirement height of medium;
(3) disinfecting time, because of the operating frequency height, the blanking time between the tested patient is very short, usually about 1 minute, kill bacteria simultaneously in short time like this, the disinfectant of mycete and virus is not also gone public at present.
CN1108956A discloses " coupling agent for medical ultrasonic diagnostic probe and preparation method thereof ", coupling agent with this method preparation is made up of thickening agent NS-90, solubilizing agent tween 80, disinfectant 1522, antibacterial sorbic acid, inclusion compound α-CD, spice, pigment, can play the sterilizing effect, avoid cross infection, and harmless to the person, to the instrument probe not damaged.But preparation technology is comparatively complicated, need add the water stirring during use and leave standstill, and is not too convenient.
Facts have proved, contain 2,4,4 '-three excessive chloro-2 '-dihydroxy diphenyl ethers, mucosa is had the strong impulse effect at medical ultrasonic coupling agent.In order to strengthen safety management to the skin and mucous membrane disinfection agent, the notice that the part composition value of limiting the quantity of is stipulated on April 6th, 2006, Chinese Ministry of Public Health was about issue skin and mucous membrane disinfection agent is clearly stipulated: in skin antiseptic 2,4,4 '-three chloro-2 '-dihydroxy diphenyl ether concentration (W/V) of limiting the quantity of is 2.00%, in the mucosa disinfectant 2,4,4 '-three chloro-2 '-dihydroxy diphenyl ethers concentration (W/V) of limiting the quantity of is 0.35%.Under such condition of limiting the quantity of, it is not enough only adopting 2,4,4 '-three chloro-2 '-dihydroxy diphenyl ethers to come kill bacteria, mycete and virus, can not reach disinfection sterilizing type medical supersonic couplant and not only be fit to skin degerming, but also has been fit to the requirement of mucosa disinfectant.
Summary of the invention
The purpose of this invention is to provide a kind of disinfection sterilizing type medical supersonic couplant, it does not have any corrosivity and swellability to ultrasonic probe, and soaking-free can reach disinfective action, and is easy to use; Disinfection time is short, can carry out sterilizing to ultrasonic probe in whole testing process, both has been fit to the sterilization to skin, is fit to the sterilization to mucosa again, reduces the cross infection risk, and the person under inspection is healthy in protection.
Another object of the present invention provides a kind of preparation method of disinfection sterilizing type medical supersonic couplant, and this preparation method operation is simple, uses equipment investment few.
A kind of disinfection sterilizing type medical supersonic couplant of the present invention, the percentage by weight that contains active ingredient is:
2,4,4 '-three chloro-2 '-dihydroxy diphenyl ethers (Triclosan, molecular formula: C 12H 7Cl 3O 2) 0.05-2%, its effect is kill bacteria, mycete and virus;
R-polysaccharide 0.1-2%, its effect is collaborative 2,4,4 '-three chloro-2 '-dihydroxy diphenyl ether kill bacteria, mycete and virus;
Propylene glycol (Dipropylene Glycol, molecular formula: C 3H 8O 2) 2-7%; Its effect is dissolving 2,4,4 '-three chloro-2 '-dihydroxy diphenyl ethers, collaborative 2,4,4 '-three chloro-2 '-dihydroxy diphenyl ethers and R-polysaccharide kill bacteria, mycete and virus;
Glycerol (Glycerine; Glycerol, molecular formula: C 3H 8O 3) 2-7%, its effect is collaborative propylene glycol dissolving 2,4,4 '-three chloro-2 '-dihydroxy diphenyl ethers, lubricated skin;
Crosslinked polypropylene diluted acid resin (Carbomer, molecular formula: 0.6-1.5% [CH2-CH-] N-COOH), its effect is to form gelatinous polymer substance;
Distilled water 80.5-95.25%, its effect is dilution;
In addition, add the triethanolamine of above-mentioned gross weight 0.8-1.2%, its effect be in and crosslinked polypropylene diluted acid resin, make the couplant finished product be neutral.
The present invention has kept the character and the coupling function of conventional medical ultrasonic coupling agent, through up to a hundred tests, in numerous disinfectant, filter out two kinds internationally recognized, to environment and body harmless, to silastic product and the non-corrosive efficient germicide 2 of metallic article, 4,4 '-three chloro-2 '-dihydroxy diphenyl ether and R-polysaccharide, and by after propylene glycol and the glycerol dissolving, on the traditional product basis, the sterilization type medical ultrasonic coupling agent of new generation of the transparent gel-form of preparing.The present invention fill a prescription all raw materials all be through checking to human body and environmentally friendly Green Product, chemical reaction does not take place and produce new harmful substance each other.
The present invention can kill pathogenic microbes such as various bacteria, fungus, virus simultaneously, reaches the dual sterilization to ultrasonic probe and skin.
(1) efficient germicide 2,4, and 4 '-three chloro-2 '-dihydroxy diphenyl ether and R-polysaccharide do not have any corrosivity and swellability to ultrasonic probe, can be used for the sterilization of ultrasonic probe fully;
(2) with scientific methods biocide is dissolved, be molecularity and be distributed in the couplant that is transparent gel-form, become the gel disinfectant, itself is aseptic condition product, make the ultrasonic probe soaking-free can reach disinfective action simultaneously, solved ultrasonic probe sterilised medium problem;
(3) ultrasonic probe begins to detect the patient to detecting end Zi contacting couplant, and ultrasonic probe is under the disinfection all the time in whole testing process, has thoroughly solved and can not realize effective disinfectant problem in the short time.Both be fit to sterilization, be fit to sterilization again mucosa to skin.
